Chintu Lai, C. A. Onions
1976, Report
This report is a program documentation to the latest revision (1975) of the unsteady open-channel flow simulation model by the method of characteristics, Version 13 in the program series, which employs a multiple-reach scheme treating each subreach as a prismatic shape. A long waterway of variable cross section, properties and...

Thermal effects on fish ecology
Charles C. Coutant
1976, Book chapter, Encyclopedia of Environmental Science and Engineering
Of all the environmental factors that influence aquatic organisms, temperature is the most all-pervasive. There is always an environmental temperature while other factors may or may not be present to exert their effects. Fish are, for all practical purposes, thermal conformers, or obligate poikilotherms. That is, they are able to...

The previous U.S. Geological Survey Catalog-Indexing System was by map number...
Selected hydrologic data, Chester County, Pennsylvania
Laurence J. McGreevy, Ronald A. Sloto
1976, Report
This report presents selected hydrologic data collected during a study of the ground-water resources of Chester County, Pennsylvania. The study was made during 1973-76 by the U. S. Geological Survey in cooperation with the Chester County Water Resources Authority. This report is intended to make the data conveniently available and...

Change in methylene blue active substances and chloride levels in streams in Suffolk County, New York, 1961-1976
Stephen E. Ragone, August A. Guerrera, W.J. Flipse Jr.
1976, Open-File Report 76-600
Since 1961, concentrations of methylene blue active substances and chloride were measured in samples collected at 67 sampling stations on 44 streams in Suffolk County, Long Island, New York. Changes in the concentrations of these constituents and calculated chloride/methylene blue active substances ratios are reported. Although many factors--the 1962 to...
Geohydrology and water supply, Shemya Island, Alaska
Alvin John Feulner, Chester Zenone, K. M. Reed
1976, Open-File Report 76-82
Sheyma Island, Alaska, was occupied as a military base in 1942. Since that time, potable water has been supplied by streams, lakes, wells, and in the late 1950's, a gallery system. The island is a low-lying, wave-cut platform composed of pyroclastic and volcanic rocks with some intrusives. Bedrock is overlain...
Conditions in the deeper parts of the hot spring systems of Yellowstone National Park, Wyoming
Alfred Hemingway Truesdell, Robert O. Fournier
1976, Open-File Report 76-428
Yellowstone thermal areas are scattered over an area of nearly 50 x 60 kilometers (Fig. 1) and contain waters of diverse compositions. This has lead to the implicit assumption that Yellowstone consisted of discrete hydrothermal systems (e.g., Fournier and Truesdell, 1970). It is the purpose of this paper to suggest...

Optimum level of dietary biotin for growth, feed utilization, and swimming stamina of fingerling lake trout (Salvelinus namaycush)
H. A. Poston
1976, Journal of the Fisheries Research Board of Canada (33) 1803-1806
Triplicate lots of fingerling lake trout (Salvelinus namaycush) held at 9 C for 20 wk were fed a semipurified basal diet supplemented with 1% spray-dried egg white or d-biotin at concentrations of 0.1, 0.5, 1.0, or 5.0 ppm. Trout fed the basal diet, either alone or with egg white, grew more slowly and...
Fine structure of an unidentified protozoon in the epithelium of rainbow trout exposed to water with Myxosoma cerebralis
S.B. Daniels, R. L. Herman, C.N. Burke
1976, Journal of Protozoology (23) 402-410
An intracellular protozoon was discovered in the epithelium of young rainbow trout (Salmo gairdneri) exposed for as short a time as 1 hr to water known to contain infective stages of Myxosoma cerebralis. Light- and electron-microscopic examination of this tissue revealed what appeared to be a proliferative stage (presumptive schizont) of a...
Utilization of satellite data for inventorying prairie ponds and lakes
E.A. Work, D.S. Gilmer
1976, Photogrammetric Engineering and Remote Sensing (42) 685-694
By using data acquired by LANDSAT-1 (formerly ERTS- 1), studies were conducted in extracting information necessary for formulating management decisions relating to migratory waterfowl. Management decisions are based in part on an assessment ofhabitat characteristics, specifically numbers, distribution, and quality of ponds and lakes in the prime breeding range. This...
Relative effect of two dietary water-soluble analogues of menaquinone on coagulation and packed cell volume of blood of lake trout (Salvelinus namaycush)
H. A. Poston
1976, Journal of the Fisheries Research Board of Canada (33) 1791-1793
Triplicate lots of fingerling lake trout (Salvelinus namaycush) (initial mean weight, 5.3 g) were fed a basal, semipurified diet, or this basal diet supplemented with either 1.0 or 2.0 ppm of either menadione sodium bisulfite (MSB) or menadione dimethylpyrimidinol bisulfite (MPB) for 18 wk at 14 C. Neither form of vitamin K had a...
Fish diseases and parasites in relation to the environment
G. L. Hoffman
1976, Fish Pathology (10) 123-128
Although some diseases are not affected by subtle environmental changes, others are. Factors which may influence infection or the course of disease are: temperature, gaseous supersaturation, oxygen deficiency, mechanical and physiological trauma of the fish, malappropriate water chemistry, pollution, eutrophication, media for spore retention, and presence of intermediate hosts. Aviatminoses...
Infection and mortality in captive wild-trapped canvasback ducks
R. M. Kocan, Matthew C. Perry
1976, Journal of Wildlife Diseases (12) 30-33
Fungal, bacterial and malarial infections, as well as malnutrition caused heavy mortality in a group of wild-trapped canvasbacks (Aythya valisineria) held in 10 × 3 × 2 m open water pens. Deaths occurred between 21 and 158 days after confinement and were associated...
Vitamin E and selenium interrelations in the diet of Atlantic salmon (Salmo salar): Gross, histological and biochemical deficiency signs
Hugh A. Poston, G. F. Combs Jr., Louis Leibovitz
1976, Journal of Nutrition (106) 892-904
Either simultaneous or separate dietary deficiencies of vitamin E and selenium in Atlantic salmon during first 4 weeks of feeding caused twice the mortality shown in fish fed both supplemental vitamin E (0.5 IU/g dry diet) and selenium (0.1 µg/g). Subsequent dietary repletion with both vitamin E and selenium significantly...

Geologic history of Cape Cod, Massachusetts
Water Resources Division, U.S. Geological Survey
1976, Report
Cape Cod, a sandy peninsula built mostly during the Ice Age, juts into the Atlantic Ocean like a crooked arm. Because of its exposed location, Cape Cod was visited by many early explorers. Although clear-cut evidence is lacking, the Vikings may have sighted this land about 1,000 years ago. It...
Avian botulism epizootiology on sewage oxidation ponds in Utah
Daniel W. Moulton, Wayne I. Jensen, Sondra K. Stewart
1976, Journal of Wildlife Management (40) 735-742
In the microenvironment concept of avian botulism epizootiology, it is hypothesized that invertebrate carcasses may serve both as a substrate for toxin production by Clostridium botulinum type C and as a vehicle for toxin transmission to water birds. We field-tested that hypothesis by attempting to induce botulism in wing-clipped mallard...
